The HI-97106 is a compact and versatile low, medium, high, and ultra-high range photometer designed to accurately determine chemical oxygen demand. Suitable for field or bench measurements in the water and wastewater industries, plus other industries wanting to measure COD.
Also this instrument is a waterproof portable photometer with an advanced optical system that uses a Light Emitting Diode and a narrow band interference filter for accurate, repeatable readings.
The optical system is sealed from outside dust, dirt, and water. The meter uses an exclusive positive-locking system to ensure that the vials are placed into the holder in the same position every time.
With the CAL Check™ functionality, users are able to validate instrument performance at any time. Hanna Instrument’s CAL Check cuvettes are certified against NIST-traceable reference instruments.
The built-in tutorial mode guides users step-by-step through the measurement process. The tutorial mode includes all steps required for sample preparation, the required reagents, and quantities.
